摘要： A process is described for producing an M41 S family molecular sieve. The process comprises preparing a synthesis mixture capable of forming said molecular sieve in a reactor, which is equipped with a mixer having a Froude number of at least 1, said synthesis mixture having a solids content of at least 20 wt%. The synthesis mixture is heated in the reactor while agitating the mixture with said mixer to form a product mixture comprising water and crystals of said molecular sieve material. Thereafter at least part of the water is removed from the product mixture in the reactor so as to decrease the water content of the product mixture inside the reactor by at least 5 wt%.

摘要： In a process for producing a molecular sieve material, water, at least one source of an oxide of a tetravalent and/or a trivalent element and at least one structure directing agent is mixed in a reactor equipped with a mixer having a Froude number of at least 1, to produce a molecular sieve synthesis mixture having a solids content of at least about 20 wt%. The molecular sieve synthesis mixture is heated in the reactor while agitating the mixture with said mixer to form crystals of said molecular sieve material and the molecular sieve crystals are subsequently recovered from the reactor.

摘要： This disclosure relates to a novel method of making and recovering M41S family molecular sieve materials using synthesis mixtures having high solids-content and without a purification step. The solids-content, for example, is in a range from about 20 wt.% to 50 wt.%. The method also includes the step of mixing at least a portion of the M41S made with another material to form a composition, wherein the amount of said material to be mixed with said M41S product is such that said composition having less than 10 wt.% free fluid. The material mixed with the M41S made includes metal oxides, metal nitrides, metal carbides and mixtures thereof, as well as absorptive material capable of absorbing mother liquor and selected from the group consisting of carbon silica, alumina, titania, zirconia and mixtures thereof. The amount of the wastewater generated by this novel method is reduced by at least 50% to as much as 100% as comparing with conventional method of making M41S materials. By reducing and/or eliminating at least a portion of the wastewater generated in the synthesis product, the new method reduces cost of making of M41S materials and provides a more environmentally-friendly synthesis product.
